But you will ask, how do you increase intensity by 3-5% once you can do 12 reps in approximately 60 seconds? The answer is to switch bilateral exercises to unilateral exercises, e.g. changing push-ups to staggered push-ups to one-handed push-ups or changing squats to "pistols" ("The Naked Warrior" (Pavel Tsatsouline)). As I progress with this experiment I'll detail some ideas for increasing intensity.
